I didn't say anything about a particular way of solving this
problem.  I just explained why turning off the timers avoid
wasting power because you said, "Turning off the timer does not
prevent the above-mentioned loop from running.  So how would this
avoid wasting power?"

BTW, stopping/suspending timers does not avoid Emacs to wake up
in a short period on some ports, depending on how its `select'
emulation is implemented.  At least, this applies to the NS port
because it does periodic polling inside its `select'
implementation when there are some subprocesses or network
connections.  The Mac port does not have this drawback.  I'm not
sure about the W32 port.
